FAQ
If my opponent has [Mr.3(Galdino)] on his field, and I have [Monkey.D.Luffy] on mine, can I use this card's [Main] effect to ensure up to 1 of my opponent's rested Characters with a cost of 6 or less will not become active in my opponent's next Refresh Phase?
No, you cannot.
If my Leader has an effect that reads "is treated as a card with all card names, types, and attributes," but I do not have a [Monkey.D.Luffy] or [Mr.3(Galdino)], can I still prevent up to 1 of my opponent's rested Characters with a cost of 6 or less from becoming active in my opponent's next Refresh Phase?
Yes, you can.
